IMPROVEMENT IN VENTILATORS .'EQR RAILROAD WATER-CLOSETS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all 'whom t may concern Be it known that I, FRANKLIN H. BROWN, ofOhicago, Cook county, and State of Illinois, have invented a new andimproved Ventilator for Water-Closets in Railway Passenger-Cars; and Ido hereby declare that the following is a clear and eXactvdescription ofthe same, reference being had to the accompanying drawings, and to theletters of referencemarked thereon', which form a-paxt of thisspecification.

The drawing represents a vertical central section of my invention,clearly representing its various parts, and showing the 'direction ofthe currents of airby arrows.

To enable those skilled inthe art to make and use my invention, I willproceed to describe its construction and operation.

I connect the wind-gatherer, or bonnet, D, to the common water-closethopper, or casing B, by means of the pipe A, passing through the roof Rof the car.

I also make one or more openings, x z, in the side of the casingV B,underneath the seat E, and prefer them to be above the lower end of pipeA.

I mount the valve a a (in ythe common wind-gath erer) upon the shaft i,and bearings g g, and the force of the wind causes it to shift from oneto the other side of pipe A, as the car is made to move in one or theother direction. v

IY improve the valve a a by curving its upper sides ont, as shown,forming a curved elbow, and thereby facilitating the passage of air frombonnet D to pipe A.

When the oars are set in motion, the air is forced in at D, down pipe A,.throughthe casing B, and escaping at the bottom, as shown by thearrows.

Air will be drawn in from the room through openings x x, and thus theventilation will constantly take place while the cars are in motion,whetherthe cover O be up or down, and the closet will be kept free fromfoul smells.

In the Water-closets 'now in use upon railway-cars, the air isfrequently forced up through the hopper, and into the room, while thecars are moving, making it offensive to persons in the closet or in itsimmediate vicinity, and very annoying to any one wishing to sit WM. L.FAXON, H. P. PARMELEE.
